Indeed.
A subtle difference is that we use the Unicode version of this API.

I know this library as doing a lot of cool things for the integration with the 
OS but I was not aware there was an implementation of processes forking. I 
thought it used one of the existing library to do that.

I think you are right on this point. I have the same feeling.
Also, OSSubprocess is now the recommended way to fork processes on Linux like 
systems, and there is no support yet for Windows, I took the opportunity to 
create the OSWinSubprocess project that could be easily merged into 
OSSubprocess once it gets all required features. I based my work on a PR done 
on Pharo Launcher by Keldon Alleyne. If I knew about the process support in 
OS-Windows, I would for sure, at least, had a look at it and possibly re-use it.

I see you have some support for pipes / streams. If you are willing to we could 
work together to merge both implementation. The only thing is that we should 
keep the OSSubprocess API when possible to allow a merge with it in a future.
WDYT?

Christophe.

x64: 64 bits version
x86: 32 bit version
For OS X, choose one of these with a dmg extension. The recommended version is 
always the 64-bits one.

[ducasse]

It would be good to add this in the awesome documentation.
